Shoutout to RX8 Upgrades for the greddy radiator + cap. Hit him up if u need new top quality rx8 parts, hes the man
Fitted these bad boys up today new exhaust surrounds & the original Mazda chrome finishers. Mint!! Thanks RX8 Upgrades for the hard to get parts!
Just installed my spanking new Autoexe Stainless Muffler, and here's a short take of my initial impressions: The Autoexe catback is lovely - very unique 2 box design and the tips are the tapered kind (ie cut at an angle) each lasercut with the Autoexe logo. Very nicely polished midpipe which connects beautifully (and easily) with the exhaust outlet. Most importantly, the exhaust tips have a perfect visual alignment, unlike other exhausts i've seen where one tip protrudes out more than the other. The Autoexe definitely doesn't have this problem. Also, the 2 box design has a lower profile than stock. Previously, i used to scrape and even dent the exhaust box when clearing humps or even parking - not so with the Autoexe. The Autoexe performs really well, at least on my AT. There is a noticable increase in low end torque, and the car just feels substantially lighter. Revs are much more responsive, and the slight lag felt when launching the car seems to have melted away. Linear acceleration is also much faster (at least across 1st 3 gears), and i'm reaching 120-130kmh much faster on 2nd gear alone (NB mine is the 4spd AT). I'm very pleased with the low-torque gains on the Autoexe - finally i have that slight 'lurch' from start which the manuals seem to have, but the ATs don't. The Autoexe starts off idle with a really low, bassy growl. When first installed, it was barely audible, but sounds louder now. In time, the db will increase to an extent. On higher RPM revs, exhaust sounds deep and wet, and def not those shrilly Remus' we hear on the expressways from time to time. Installation was a breeze, and took under an hour at Monster Garage at Ubi, who's the only authorized dealer in Singapore, so these guys know their stuff. The torque/hp improvement was a shocker esp on low end, esp when mine's an AT. I've heard of bros installing Fujitsubos and HKSs that have either no or negative benefit. In this respect, I'm mighty pleased with the Autoexe. Sound is not loud, but a soft low bassy growl when idle, which develops into a mature wet sound at higher revs.
So happy with these. Thanks RX8 Upgrades

I love my setup. Haha had cops give me the thumbs up at a red light. Lol
A Mazda RX8 fuel pump replacement or fuel system component for owners maintaining or upgrading their car. Reliable fuel delivery is non-negotiable for a rotary engine that depends on precise, consistent fuelling across its rev range.
A worn or failing pump starves the engine at precisely the moment it demands the most. That moment might be climbing toward the redline on a back road, or holding throttle on a long freeway run. Because of this, Australian owners need a replacement with confirmed fitment and known condition, not a used pump pulled from a wrecked car.
A 13B-MSP runs on a combustion cycle that differs fundamentally from a piston engine. It relies on precise, consistent fuelling at every point across its rev range. There is no slack for momentary lean conditions. For example, an in-tank pump that is marginal under load will show up as hesitation or lean stumbles long before it fails completely. Therefore, replacing the fuel pump at service intervals keeps the fuel system ahead of the problem rather than reacting to it.
Fitment confirmation is the first step before anything else. Not every fuel pump suits every application. However, owners sourcing a replacement should check individual product details carefully against their vehicle’s current configuration.
Beyond a like-for-like OEM-spec replacement, higher-output options are also available for builds where increased fuel flow supports additional modifications. The DeatschWerks DW200 Mazda RX8 fuel pump is a well-regarded choice for owners wanting a performance-spec unit in Australia. Developed by DeatschWerks, it carries a known flow rating and a track record in modified applications.
For owners searching for a Mazda RX8 fuel pump or broader fuel system components in Australia, local availability matters for lead times and fitment support. As a result, each product listing in this range includes specific fitment information, use it. If you are comparing options or have questions about which pump suits your build, the answers are in the individual product pages, not assumptions about interchangeability.
The RX8 fuel system range includes in-tank fuel pump options suited to maintenance replacements and upgrade paths. Each product carries its own fitment details, so check the individual listing to confirm the pump suits your specific vehicle configuration before ordering.
Not all RX8 fuel pumps share the same fitment across Series 1 and Series 2 vehicles. Always review the stated fitment on the individual product page before purchasing, as assuming interchangeability can result in an incompatible part.
The DeatschWerks DW200 is listed as an option within the RX8 fuel pump range. Check the individual product details carefully to confirm fitment against your vehicle's current setup and intended use before committing to purchase.
A new fuel pump gives you a known-condition starting point, whereas a used pump carries an unknown service history and wear state. For a component as critical to reliable fuel delivery as the in-tank pump, starting fresh removes an unnecessary variable from your build or maintenance work.
Common signs of a deteriorating RX8 fuel pump include hard starting, inconsistent idle, hesitation under load, and difficulty maintaining fuel pressure. Because rotary engines are sensitive to fuel delivery consistency, addressing pump condition early is worthwhile rather than waiting for a full failure.
The category includes options suited to both straightforward maintenance replacements and owners planning a broader fuel system upgrade. Review each product's stated intended use and flow rating to determine whether it matches your engine's current or planned state of tune.
Replacing an RX8 in-tank fuel pump typically requires draining or lowering the fuel level, removing the rear seat or access panel, and disconnecting the pump assembly from the sender unit. A fuel pump lock-ring removal tool is generally needed. Refer to the individual product instructions and a workshop manual for your specific vehicle.
